Adapter for connecting the control unit "on the table", switching power supply voltages and GPT1, GPT2, as well as generating BOOT and CNF1 signals. Fully compatible with the CombiLoader bootloader and can also be used manually with any bootloader that has "manual control logic".
Control elements:
The device is equipped with three switches for operation in different modes.
- GPT switch.
When this mode is activated, the signal lines 7 and 15 of the DiaLink connector are connected to the DB-15 connector (GPT1 and GPT2), and the power supply is simultaneously disconnected from the DiaLink connector. It is used for reading the password in GPT mode. In the off state, the signal lines 7 and 15 are connected to the DB-15 connector (K-line and L-line), and the GPT1 and GPT2 lines are de-energised.
- POWER switch, power control.
The device has three power supply modes for the ECU:
OFF - power off, allows to disconnect all power and control signals from the DB-15 connector.
MANUAL - power on, provides power to the VECU and VKEY terminals, as well as control outputs depending on the selected BOOT switch mode.
AUTO - automatic control, in this mode, power control is performed by the CombiLoader.
- BOOT switch, simultaneous control of BOOT and CNF1 signals (3.3 volts):
OFF - power off, allows to disconnect all control signals from the DB-15 connector.
MANUAL - power on, pulls BOOT to the signal ground, and CNF1 to +3.3 volts.
AUTO - automatic control, in this mode, simultaneous control of signals is performed by the bootloader.
The device has built-in current-limiting resistors on the signal lines:
- RESET - 510 Ohm
- BOOT - 510 Ohm
- CNF1 - 510 Ohm
- CAN - 120 Ohm
Connectors:
The device is equipped with connectors for peripheral connection.
The DC connector is intended for power supply.
The J2534 connector is designed for connecting the corresponding interface with the OBD-II connector.
The connector has the following pinout:
- 4 GND
- 5 GND
- 6 CAN-H
- 7 K-LINE
- 13 VPP
- 14 CAN-L
- 15 L-LINE
- 16 POWER
The DB-15 connector is designed for connecting the ECU.
Attention! DB15 cable is not included and must be purchased separately.
The connector has the following pinout:
- 1 RESET BROWN
- 2 VPP PURPLE
- 3 GPT2 ORANGE
- 4 CNF1 BLUE

Indicators:
- The GPT LED indicates the activation of the corresponding mode.
- The VECU and VKEY LEDs indicate the presence of VECU and VKEY voltages.
- The 12V LED indicates the presence of power supply voltage.
- The BOOT LED indicates the presence of pull-ups on CNF1 and BOOT.
